No wipers or climate control - 26/08/2019 17:27
Hi guys I’ve got an intermittent problem with my 20vt plus wipers/washers working intermittently but when they’re not working neither is my climate control, when it kicks in both work again! Tried a spare motor not that! fuses all good, could it be a relay issue? Can’t think of anything else! Any help would be greatly appreciated.
Many thanks steve

Hi Steve, this won't be much help I'm afraid but interesting nonetheless.
My main beam and central locking button both stopped working. I checked the fuses which were fine but after I did so both started working again.
Similar to your problem so looking forward to seeing how this thread developes.

Thanks for the response I’ve checked rechecked all the fuses dozens of times, taken the relays out put them back in, checked the engine fuses but still the same 🙄 don’t understand why the washers/ wipers and climate control both don’t work? I assume they are on different circuits 🤔

In the passenger footwell to the right of the ecu is the fan control unit. Look for the plug with several wires going in and give it a wiggle with the fan turned on (not to "Auto" setting)
Does your fan work on Auto at all? Or at MIN or MAX settings?
I'll try and find a pic of the fan control...

Here you go, this is the fan resistor location

Thanks Edinburgh I’ll give it a whirl the fan doesn’t work on any settings at all until everything kicks in then both work wipers, fan but seems to go off if I have both on!

To confirm, when both are fully working independently, if you have the fan on and you switch on the wipers the fan goes off?

It's a long shot but the thin wires in the loom which snakes up behind the radio sometimes get /strippedsnagged by the really sharp edges of the frame.....maybe worth reaching up behind there and giving that a wiggle with the wipers/fans ON (but "not working")

Usually when they are working if I use both at the same time they both go off!

At this point I'd need to await the arrival of the auto-elecricians on here I'm afraid, sorry

The wipers, screen washer pump and climate control are all powered via fuse #3 (marked with wipers symbol) in fuse box, so most likely a dodgy connection at the fuse holder or at the connector block where that power line exits on the back of the fuse box, which is a light blue/red striped cable on connector "I".

I did see this in the FAQ info section but the OP implied he'd checked all fuses

The fuse itself may be OK as far as not being blown, but it could still have a dodgy connection if the fuse box socket is corroded, loose or damaged, or the fuse legs are corroded. Or sometimes you can have a dodgy connection at the big plugs coming out the top/back of the fuse box, so dropping the complete box and checking around the light blue/red wire on connector "I" would be worth a look.
If the problem is intermittent then presumably the fuse isn't blown, but more likely there's a dodgy connection somewhere on the power or ground side and given all the problem components are on the same power circuit that would be the obvious place to start checking, from the fuse connections back.

Happy to oblige
Incidentally your profile says you have a "2003" 20vt - are you sure?

Re: No wipers or climate control - 27/08/2019 21:26
Yes absolutely

Ok, officially Fiat ceased production of the Coupe in 2000..."Y" registrations finished in August 2001.
So out of interest - if yours isn't a personalised plate - what letter prefix do you have?
Perhaps your vehicle was first "registered" in 2003?

Could it be
this car or another from the same "batch"?

Re: No wipers or climate control - 28/08/2019 23:52
Yes it was first registered 03 Simon and yes Dave that’s my car

It's a pity, trawling through previous related threads, that all the pics of this seem to have been zapped by Photobucket

Re: No wipers or climate control - 29/08/2019 20:48
Yes I noticed I’ll try and get some up there
